REPLICATION INFORMATION

These replication files allow one to replicate the tables, figures, and results reported in "A Mixture Model for Middle-Category Inflation in Ordered Survey Responses"

There are two zipped replication file folders: one corresponds to the analysis presented in the main paper ("Main Paper Replication Files.zip") and the second corresponds to the analysis reported in the supplemental appendix ("Web Appendix Replication Files.zip").


"Main Paper Replication Files.zip" contains:

1. A sub-folder labeled "Table 1", which includes the main dataset needed for the EU-Support analysis ("EUKnowledge.dta") and the r-code used for producing the OP, MiOP, and MiOPC models of EU-Support that are reported in Table 1 of the main paper ("Table 1.R").
2. A sub-folder labeled "Figure 1", which includes the auxiliary EU-Support results dataset ("MIOPC.Main.Results.dta", which was produced by "Table 1.R") needed for producing "Figure 1: ROC Curves of MiOPC pr(inflated) and uninformed respondents" in our main paper.
3. A sub-folder labeled "Figures 2-3", which includes the original dataset needed for the EU-Support analysis ("EUKnowledge.dta"), two R-scripts used to calculate the OP & MiOPC marginal effects for our two independent variables of interest ("Female Marginal Effects Calculations.R" & "Discuss Politics Marginal Effects Calculations.R"), a set of resultant marginal effects datasets, and the R-code needed for using these resultant datasets to create the boxplots reported in Figures 2-3 of the main paper ("Figures 2-3.R").


"Web Appendix Replication Files.zip" contains:
1. A sub-folder labeled "EU Support Robustness Models" which includes the R-code used to generate the robustness models for EU-support that were reported in Tables A.3-A.8 of the supplemental appendix (along with the main EU-Support Dataset: "EUKnowledge.dta"), as well as the EU-support marginal effects table reported in Table A.9.
2. A sub-folder labeled "Monte Carlo Results" which contains the R-code needed for running Monte Carlo Experiments 1-6, along with the R-code used to produce the Monte Carlo tables (A.1-A.2) and figures (A.1-A.4) that are reported in the supplemental appendix.
3. A sub-folder labeled "Anit-Nuke Mvmnt Support" which contains the Anti-Nuclear Movement Support dataset ("mainEuroDataset.dta"), along with the code used to create the OP, MiOP, and MiOPC models of Anti-Nuclear-Movement Support reported in Table A.10 of the supplemental appendix ("Table A.10.R"), and the education marginal effects boxplots ("Figure A.5.R").
4. A sub-folder labeled "Support for Trade", which contains the dataset ("formatted_MRdata.dta") and R-code ("Table A.11.R") used to create the OP, MiOP, and MiOPC models of trade-support that are reported in Table A.11 of the supplemental appendix.
